This document provides MATLAB code to compute several functions: (1) It defines symbolic variables and uses limit to find one-sided limits as x approaches 0. (2) It defines a function of sin(x)/x and takes its derivative. (3) It defines anonymous functions for exp(-2*x)sin(x), exp(-x^2), and (1+x^4)^0.5 and computes their integrals from 0 to infinity or 0 to 1.

Which of the following was NOT a goal of Titchener’s psychology? A. Discover how these elements are grouped. B. Discover the purposes of the various elements. C. Determine the causes of the element groupings. D. Identify the elements of consciousness. Solution The below paragraph describes the idealogy of Titcher. Titchener\'s ideas on how the mind worked were heavily influenced by Wundt\'s theory of voluntarism and his ideas of Association and Apperception (the passive and active combinations of elements of consciousness respectively). Titchener attempted to classify the structures of the mind in the way a chemist breaks down chemicals into their component parts—water into hydrogen and oxygen, for example. Thus, for Titchener, just as hydrogen and oxygen were structures, so were sensations and thoughts. He conceived of hydrogen and oxygen as structures of a chemical compound, and sensations and thoughts as structures of the mind. A sensation, according to Titchener,[2] had four distinct properties: intensity, quality, duration, and extent. Each of these related to some corresponding quality of stimulus, although some stimuli were insufficient to provoke their relevant aspect of sensation. He further differentiated particular types of sensations: auditory sensation, for example, he divided into \"tones\" and \"noises.\"[3] Ideas and perceptions he considered to be formed from sensations; \"ideational type\" was related to the type of sensation on which an idea was based, e.g., sound or vision, a spoken conversation or words on a page.[4] Titchener believed that if the basic components of the mind could be defined and categorised that the structure of mental processes and higher thinking could be determined. What each element of the mind is, how those elements interact with each other and why they interact in the ways that they do was the basis of reasoning that Titchener used in trying to find structure to the mind. As per his ideology the only factor NOT valid is B..

You discover a new kind of fungus with large, square-shaped spores. What can you conclude about dispersal in this species? Question 5 options: The spores are composed of diploid cells The spores likely get propelled through the air The spores may require animals to disperse them The spores likely swim through the wate The spores are composed of diploid cells The spores likely get propelled through the air The spores may require animals to disperse them The spores likely swim through the wate Solution (Ans) ......The spores likely get propelled through the air. There are several different mechanisms by which fungi release their spores into the air which then allows them to be dispersed by wind,other mechanisms that serve the same functions of initially ejecting the spores into the air so that they may be picked up by air currents.The ascospores are forcibly ejected through the top of the asci and are then carried away by wind. Spores are initially ejected into the air is the mechanism used by certain puffballs,puffballs are also members of the Basidiomycota the basidium does not forcibly eject the basidiospores into the air to be carried away with the wind..

A5OO Solution 1) the process of finding information, a place, or an object,especially for the first time, or the thing that is found: the discovery of electricity Leonardo made many scientific discoveries. a journey/voyage of discovery The discovery of a body in the undergrowth started a murder enquiry. More examples Scientists are on the brink of a major new discovery. The discovery of oil brought many benefits to the town. Various ecological issues have come to the fore since the discovery of the hole in the ozone layer. The two scientists both made the same discovery independently, at roughly the same time. Word of the discovery caused a stir among astronomers. 2) to remove or take away someone or something: A move towards healthy eating could help eliminate heart disease. We eliminated the possibility that it could have been an accident. The police eliminated him from their enquiries. to defeat someone so that they cannot continue in acompetition: He was eliminated in the third round of the competition. slang to murder someone: A police officer was accused of helping a drug gang eliminate rivals. More examples Water helps eliminate toxins from your system. Police have eliminated him from their enquiries. The virus can never be entirely eliminated from the body. The programme will minimize, though not eliminate, the problem. She hired an assassin to eliminate her rival. 3) not being careful or giving enough attention to people or things that are your responsibility: The judge said that the teacher had been negligent in allowing the children to swim in dangerous water. 4) something that a copy can be based on because it is an extremelygood example of its type: The educational system was a model for those of many other countries. The developer plans to build a model community on the site. They created an education system on the European model. Even Chris, the very model of calmness (= someone who is usually extremelycalm), was angered by having to work such long hours. She really is a model (= perfect) student. More examples Throughout the ordeal of her husband\'s funeral, Mrs Kennedy was a model of deportment . He was the very model of a gentleman - he behaved perfectly. She seems to think that my niece is a model child, unlike my kids! The team decided to set up a sixth form college on the same model, except smaller. Jack was a superb manager and his department soon became a model for all the others to emulate. 5) the process of making a substance pure: The refinement of raw opium yields other drugs, such as morphine. a small change that improves something: These refinements have increased the machine\'s accuracy by 25 percent. Clearly, the hypothesis does need some refinement, in the light of these surprisingresults. 6) a place from where a person can look at something,especially at an area of n.

Prerequisites — Classes or Knowledge Required for this Course Successful completion of Introduction to Project Management Principles and Practices Coursera Specialization courses: Initiating and Planning Projects, Budgeting and Scheduling Projects, and Managing Project Risks and Changes. Course Objectives Upon completing this series, you should be able to: • Write a narrative charter statement • Create a work breakdown structure • Sequence project activities • Build a project schedule • Create a project budget • Create a responsibility assignment matrix • Identify project risks and define responses for those risks *>Sample Projects for Use If a student does not have access to a viable project to use for this capstone, then any one of the ideas below may be used. Please note that students are meant to take these ideas and build upon them. Each student is to take the idea and come up with his or her own full project scope and boundaries. 1) A new CEO has arrived. She believes that the current company structure is ineffective. You are to be the project manager who leads her executive team in a company-wide reorganization. This reorganization includes some work to determine how the new structure will be identified, the work to gain support for this new structure at the executive level, the communications about the new structure to the entire company and a transition plan to take the company from the current structure to the new one. 2) Your company is celebrating 50 years in business. The executive team would like to take an opportunity to recognize this milestone. Their purpose is to reward employees, build morale and also let customers; future customers and competitors know about the longevity of the company and adopt a ‘we are here to stay’ type of campaign. This milestone is definitely a marketing event. The celebration should include customers and employees. Definitely there should be a big celebration, but the executive team wants more than that. They want events and announcements and campaigns going throughout the entire year. You will project manage this effort. 3) You have joined a start up company whose goal is to create an iPhone knockoff or copy. The idea is to out ‘iPhone’ the iPhone, but at 50% of the cost to the customer. You are the project manager of the team who will identify what features will go into this iPhone copy, determine how to manufacture the phones for less than the real iPhone and determine how to market this new copy. The project ends once the idea has either been abandoned or the new copy phone has been available for sale for 45 days.............. #1 Narrative Charter Statement (13 Points) Description and Directions Develop a narrative charter that includes the following sections: a.

Please don\'t answer if you cannot complete all the requirements. This question has been answered but it was incorrect!!! You are to write the following PersonalCalendar, Event and Appointment classes and other interfaces or classes as necessary. Note that there is no main method required in this assignment; a JUnit test will be used instead. Some details of the implementation are left to you. Other details are implied, but not stated directly, in the description. (That said, don\'t over think this; do the minimum required to perform the specified function.) You are to write a class PersonalCalendar. Entries in a PersonalCalendar can be either an Event or an Appointment. Entries can be added to, returned from and removed from the PersonalCalendar. An Event has a date consisting of ints for year, month, dayOfMonth, hour and minute. It also has a String description, a String location and an int duration in minutes. Events do not have attendees. Two Event objects are equal if their dates and descriptions are equal. An Appointment has a date consisting of ints for year, month, dayOfMonth, hour and minute. It has an int duration in minutes and a String description. An Appointment also has an ArrayList of Strings for attendees. Attendees can be added to an Appointment. An Appointment does not have a location--that\'s assumed to be my office. Appointment has an equals method that compares dates and descriptions to determine equality. A PersonalCalendar maintains its entries sorted by date, not the order the entries were inserted. Thus the first element of a PersonalCalendar is always the fist element chronologically, regardless of the order the elements were added. If two elements have exactly the same date and time, description is used to break the tie. (Hint: GregorianCalendar and Collections.sort. Also let your IDE help you write commonly used code.) You are to write a JUnit test to verify that a PersonalCalendar object maintains its entries in the correct order. Here are some bullets I will use in grading PersonalCalendar accepts both Event and Appointment objects PersonalCalendar does not accept objects such as String PersonalCalendar keeps its content sorted appropriately Event implements the specified function Appointment implements the specified function JUnit tests verify the following: A PersonalCalendar with a single Appointment or Event contains the expected object. A PersonalCalendar returns its objects sorted first by date and then description, regardless of the order the objects were added, and regardless of whether the items were all Events, or all Appointments, or a mixture. My JUnit test class was long, but that was mostly because I did a lot of copy/paste for test setup. None my other components were more than 50 lines of code. Solution import java.util.GregorianCalendar; import java.util.ArrayList; import java.util.HashMap; import java.util.Set; import java.util.Iterator; //Personal Calendar class PersonalCalendar { HashMap > cal.

Need help for this essay. Questions 1–4: Answer the following essay questions in one to two short paragraphs. 1. Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. 2. Compare and contrast the traits and growth patterns of opportunistic versus equilibrium populations. Provide one example of each. 3. Compare and contrast indirect versus direct values of biodiversity, and provide examples. 4. Describe two traits that represent a sustainable society and two traits of a nonsustainable society. Solution 1.The global pressure of the human population is significantly altering the natural course of many of biogeochemical cycles of our earth leading to imbalance nutrients and compounds with the usual climatic and biological feedback mechanisms. These imbalances contribute to marine dead zones, climate change, ocean acidification, and many other environmental problems.Cultural eutrophication and fish kills are mainly caused due to the lack of oxygen also known as anoxia. Although eutrophication is naturally occurring, slow and inevitable process. When humans speed up that process by adding pollutants into our ecosystem, this will cause the death and premature aging of bodies of water due to the contamination with sewage, chemicals, and fertilizers. It will also cause cause the slow death of that body of water due to anoxia killing all living things within it. 2Opportunistic species use the r-strategy. They produce millions of eggs and sperm since only a small percent will actually meet, join, and become offspring. Opportunistic species are often the first to colonize a new environment with a \"boom and burst\" growth pattern, with a short life cycle. They tend to “crash” when they run out of food, space. oxygen, sunlight, or whatever the limiting factor is in that environment. Examples are most insects. and corals. barnacles, clams. scallops and oysters. who spawn and fertilize their eggs in the water. Equilibrium species use the K-strategy. The carrying capacity ofthe environment. These species produce much fewer offspring and usually brood them andlor take care of them in other ways. The populations of these species may rst grow exponentially. but the growth levels off when they reach the carrying capacity ofthe environment. They prefer a stable predictable environment and have along life cycle. Most birds and mammals use this strategy. as well as some live-bearing sh like dogsh sharks . 3.Biodiversity is the degree of variation of life. This can refer to genetic variation, species variation, or ecosystem variation within an area, biome, or planet.Maintaining biodiversity has a direct economic value to humans, as well as indirect economic value because our ecosystem is affected by any imbalances in the environment. For example. a lack of trees will mean we don’t have enough oxygen to breath. A lack of sh will mean many animals that feed of sea creatures wil.

In the subject of cryptography Suppose a system uses a Public-Key Infrastructure with a Certificate Revocation List. A device in that system is asked to verify a certificate but cannot access the Certificate Revocation List database because of a denial-of-service attack. What are the possible courses of action for the device, and what are the advantages and disadvantages of each course of action? Solution Answer:- Cryptography : Cryptography is closely related to the disciplines of cryptology and cryptanalysis. Cryptography includes techniques such as microdots, merging words with images, and other ways to hide information in storage or transit. However, in today\'s computer-centric world, cryptography is most often associated with scrambling plaintext (ordinary text, sometimes referred to as cleartext) into ciphertext (a process called encryption), then back again (known as decryption). Individuals who practice this field are known as cryptographers. Modern cryptography concerns itself with the following four objectives: 1) Confidentiality (the information cannot be understood by anyone for whom it was unintended) 2) Integrity (the information cannot be altered in storage or transit between sender and intended receiver without the alteration being detected) 3) Non-repudiation (the creator/sender of the information cannot deny at a later stage his or her intentions in the creation or transmission of the information) 4) Authentication (the sender and receiver can confirm each other?s identity and the origin/destination of the information) Procedures and protocols that meet some or all of the above criteria are known as cryptosystems. Cryptosystems are often thought to refer only to mathematical procedures and computer programs; however, they also include the regulation of human behavior, such as choosing hard- to-guess passwords, logging off unused systems, and not discussing sensitive procedures with outsiders. The word is derived from the Greek kryptos, meaning hidden. The origin of cryptography is usually dated from about 2000 BC, with the Egyptian practice of hieroglyphics. These consisted of complex pictograms, the full meaning of which was only known to an elite few. The first known use of a modern cipher was by Julius Caesar (100 BC to 44 BC), who did not trust his messengers when communicating with his governors and officers. For this reason, he created a system in which each character in his messages was replaced by a character three positions ahead of it in the Roman alphabet. In recent times, cryptography has turned into a battleground of some of the world\'s best mathematicians and computer scientists. The ability to securely store and transfer sensitive information has proved a critical factor in success in war and business. Because governments do not wish certain entities in and out of their countries to have access to ways to receive and send hidden information that may be a threat to national interests, cryptography has been su.

Identify a critical business requirement for a small healthcare provider located in rural Florida. Also explain why you think this requirement is critical. Solution Accesss to healthcare services in every nook and corner of the world is important, especially in rural areas it is quite critical. Ideally, the residents of the area must have convenient and affordable access to the services such as primary care, behavioral heath, emergency, dental, and public health services. Each individual’s ability to access health services has a profound effect on every aspect of his or her health, yet at the start of the decade, almost 1 in 4 Americans do not have a primary care provider (PCP) or health center where they can receive regular medical services. When we talk about providing healthcare services in rural areas, there are many issues which a small heathcare provider might face and one such critical business requirement is lack of funds and quality of service compared to urban healthcare. Rural residents tend to be older, have lower incomes and are more likely to be uninsured than residents of metropolitan areas.Rural residents also are more likely to suffer from chronic illnesses than their urban and suburban counterparts. Nearly half of rural residents report having at least one major chronic illness, and chronic diseases such as hypertension, cancer, and chronic bronchitis are up to 1.4 times more prevalent in rural than in large urban areas. Due to reluctance of people to pay more for the medical services, the business of a small heathcare can severly get affected as only a handful of people will be willing to spend any part of their income on costly health services be it primary health care, mental or any other service. If there will be no funding, the business cannot flourish and the healthcare cannot invest in costly equipment which might be helpful for treatment of chronic diseases. Another critical business requirement is manpower. It is a little difficult to find efficient and skilled workforce in rural areas as most of the people are into small scale businesses or jobs such as farming, labourers etc. So it is a critical task to find the adequate workforce in rural areas..
